Said the person who is about to purchase an iPhone 6 with massively outdated specs compared to the competition ;-)
If the i6 really does only have 1GB of RAM then it isn't all that much better than the i5 and certainly not the 5S.
Specs mean nothing to me. User experience is all I care about. If another phone has 4GB of RAM, does it make it 4x faster than my iPhone 5? Definitely not.
